The Async Stream Problem

See "How can I asynchronously assign a stream after one has already been created?"

The Solution

We will develop a function called makeRequest that returns a Duplexify stream. At the same time we make the stream, we make a request to get an authorization token.

Expectations

The function will return a stream that performs as a normal request stream would, except we are able to make an async API request in front of it without even noticing.

Try It

# Start the server (if it's not running already)
$ cd stream-faqs
$ npm install
$ npm start

# Run the example
$ cd ex-async-assign
$ npm install
$ node .
